NUT-LOCK.

To all whom it may concern:

Be it known that we, I/VILLIAM D. l/VILKIN- soN and FREEMAN H. SEELEY, citizens of the United States, residing, respectively, at Finger and Brinly, in the counties ot' McNairy and Chester and State of Tennessee, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.

Our invention relates to nut locks, and has lor its object to provide certain improvements in that class of nut locks employed with a plurality of nuts, such as are used with rail joints, whereby not only will the nuts be securely locked, but the locking device will be securely retained in place.

In the accompanying dram'ng: Figure l is a perspective view of the abutting ends of two rails with our improved device in position thereon. Fig. 2 is a horizontal sectional view taken on the line of the locking bolts. Fig. 3 is a transverse sectional view taken on the line III-III, Fig. 2. Fig. Ll is an enlarged detail, perspective view oi the retaining clip.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawing the reference numerals l denote the meeting ends oi' two rails, and 2 the fish plates usually employed therewith. Passing through registering apertures in the webs of said rails and said lish plates are the bolts 3, headed on one end at Il to retain the fish plate on that side, and screwthreaded on their other ends to receive the usual nuts 5.

Our improved device consists ot a bar 6, which, when four bolts are employed, is liust long enough to contact with the inner sides oi the two end nuts, and is recessed on its under side to fit over the two intermediate nuts, as

vide a thin metal plate 7 centrally slotted at 8 from its bottom up to provide two arms, t), theslot 8 being wide enough to straddle the bolts 3.

In assembling` the device one of the plates 7 is first positioned on each oi the intermediate bolts 3, and the'nuts 5 thereof and ot the end bolts are screwed to position. The bar 6 is then brought down upon said nuts with its recesses registering with the intern mediate nuts, it being seen from Fig. 2 that said nuts and bar are slightly beveled to prevent outward movement of said bar when in position, so that said bar can be withdrawn Specification of Letters Patent.

Application led August 25, 1908.

from said nuts by an upward movement.

Patented April 2'?, 1909.

Serial No. 450,244.

lVith said bar positioned, the upper projecting edges ot the plates 7 arc bent over onto the top edge of said bar, and the lower projecting ends et their arms l) are bent around said bar and nuts to engage the 'iront faces ot the two, as shown. ly these means the bar 6 eiiectually prevents any rotation of the nuts 5, and is itself locked against any but an upward movement by the beveled iaccs ol said nuts. Said upward movement, however, is prevented by the bent over upper ends of the plates 7, while the latter are locked against upward movement by the bent lower ends oi' their arms 9 engaging their nuts 5. The device may be unlocked either by straightening the bent lower ends of said arms whereupon said har 6 and plates 7 may be removed together vertically, or by straightening the bent upper ends et said plates 7, whereupon said bar alone may be removed vertically. The bottoms of the plates 7 may be closed and apertures provided therein to [it over the bolts 3.

Having thus described our invention, what we claim as new and desire to secure by lietters Patent, is:

l'. In a nut locli, the combination with the body to be bolted, a phirality of' bolts there- 'l"or, and nuts on said bolts, o'f means lor engaging said nuts to lock them against rotation, consisting oi" a bar havingI recesses in one edge thcreoi to llit over the nuts, and means 'lor locking said nuts locking means consisting oi a slotted plate adapted to be bent over at its upper edge to engage the rccessed har and adapted at its lower end to be bent to engage the 'lace oi" said recessed bar and said nuts and to be retained in position by said nuts independently oi said nut lool;- ing means.

2. In a nut locli, the combination with the body to be bolted, a plurality of bolts therei'or, and nuts on said bolts having beveled side faces, of a locking bar having beveled surfaces `fitting against the side faces ot' said nuts to lock said nuts against rotation and to prevent withdrawal of said bar in one direction, and means for locking said bar to said nuts to prevent its withdrawal in the direction oi' its insertion, said means being held in position by said nuts independently oi said bar.

3. In a nut lock, the combination with the body to be bolted, a plurality oi bolts therefor and a beveled nut on each of said bolts, oi a flexible plate apertured to lit onto one of said bolts and inserted thereon between the In testimony whereof We aX our signabody to be bolted and the nut thereon and a tures, in presence of two Witnesses. bar having beveled surfaces fitting against WILLIAM D.
